Precise measurement and documentation of moisture content is a quality control process mandated by government agencies. Determining the moisture content can only be accomplished by analyzing small samples of the target elements using a moisture analyzer. There are several types of moisture including surface moisture, absorbed moisture, and chemically-bonded moisture. When weighing the amount of moisture, a moisture balance is required alongside the knowledge of moisture analyzer principle. If this balance is not maintained properly, the findings will be misleading which can cause serious repercussions. Below is a guide on how to maintain your moisture balance.
Step 1: Calibrate the Moisture Balance properly
Without a doubt, moisture balances are delicate equipment which can weigh milligrams of moisture and also calculate up to 0.001%moisture. As such, you should not just take them out of the box and plug them in, but rather you should put into considerations the effects of gravity which vary across the globe. In that effect, the moisture balance should be calibrated before being put to use, and recalibrated occasionally. However, you should familiarize yourself on how to calibrate the balance before embarking on the task.
Step 2: Clean the Moisture Balance Regularly and Thoroughly
Cleaning a moisture analyzer is a critical part of its maintenance process. Fortunately, the cleaning steps are indicated in user manuals. However, you need to familiarize yourself on how to disassemble and assemble the balance parts correctly. While cleaning, you need to remove sample dishes, dish holders and retainers, draft shield and the base plate. These parts should be individually washed using a soft, moist cloth without the use of aggressive cleaning agents. After a thorough cleaning, dry them with a soft cloth and allow them to stay unattached for sometimes to ensure they dry completely.
When cleaning the body of the balance, use the same procedure as above. In case there are residues or crumbs, you can remove them using a vacuum cleaner or soft brush. Additionally, you should use extreme caution to ensure that no liquid penetrates inside the device.
Step 3: Clean the Temperature Sensor
The temperature sensor is designed to conduct moisture analysis meaning that it is a very crucial and delicate part of your device. This sensor is located on the lid alongside halogen or infrared lamp. You should clean it the same way as the base unit but use extra care. However, you should not touch or damage the halogen lamp.
Undoubtedly, a laboratory moisture balance should be kept clean at all times to avoid error and misconceptions when determining the moisture content. To ensure that you clean your balance safely, familiarize yourself with moisture analyzer principle to avoid interfering with or damaging important elements of the balance. In doing so, the balance will give you accurate results and serve you for a longer duration.
